pituitary gigantism

Pituitary gigantism is a condition characterized by excessive growth in stature, occurring when the pituitary gland hypersecretes growth hormone during childhood or adolescence, before the long bones' growth plates have closed. This overproduction, often due to a pituitary tumor, leads to a gradual but continuous increase in height, potentially resulting in individuals reaching eight feet tall with proportionally developed bones. While muscles may be well-developed, they can later weaken. The lifespan of individuals with pituitary gigantism is often shorter due to increased susceptibility to infections and metabolic disorders. Treatment, such as surgery or irradiation of the pituitary gland, can halt further growth, but it cannot reduce existing height. If growth hormone overproduction continues after growth plates have closed, it results in acromegaly, characterized by enlargement of extremities.12
